Maybe you are among those who would use the money from a big Powerball win to cruise around the world after paying off your bills.

Maybe you’d open your own business or perhaps you would buy a great big house or three and six or seven Bentleys.

With the jackpot at a record $500 million for tonight’s drawing, a lot of people are having lottery fantasies.

No matter what the winner or winners ultimately decide, Ohio Lottery spokeswoman Marie Kilbane  suggests simmering down first.

“Take a few deep breaths, of course, to calm down,” she said. “This type of money is mind-blowing.”

Odds are heavily against you experiencing that feeling, though.

Kilbane says the odds of winning a $1 million prize is about one in 5.1 million. The odds at winning the jackpot is about one in 175.2 million.

Ohio joined the multi-state Powerball drawing in February of 2010 and has had two Powerball jackpot winners: $97 million on June 23, 2010, for a ticket sold in Curtice, near Toledo; and $260 million on June 2, 2010, for a ticket sold in Sunbury, near Columbus.

Ohio has had seven winners of Powerball’s second-tier $1 million prize in 2012. There were 16 winners in 2011, including a woman who purchased at Andes Drive Thru & Carryout in Fairborn.

All that said, no one would bother playing if they didn’t think they could win.

Here is a little advice from  Kilbane if you are that one in 175 million:

• Sign the back of your lottery ticket immediately.
• Put the ticket in a safe place.  Kilbane said it is up to the individual to determine where an appropriate place might be. Secure places include safes and safe deposit boxes.
• Talk to your financial adviser or attorney.
• Give yourself time to consider your next step.
• Go to one of the Ohio Lottery’s regional offices to claim your prize and fill out appropriate forms. It will take about four weeks to get your money.
